Univox Super Fuzz with Tone Control?

[tracer03]

Anyone have any idea if there's a layout for - or clone of - the Univox Super Fuzz with a tone control pot instead of the switch? I've searched here and a few other sites without success, and my Google-fu is weak sauce tonight...

The closest I've come is finding some old discussion about replacing the switch with a pot, and a schematic at GGG for their Super Fuzz with Mods (link here) - along with a perf layout at DIY Stompboxes (link here) - but nothing a can manage for stripboard.

Thanks in advance - again!

just take and replace the switch with a pot. lug 3 of the pot goes to Sw3 on the board, lug 2 to S2 on the board, and lug 1 to SW1 on the board. What this will do will allow you to sweep between the two tone options rather then having the choice of 1 or the other. try using a 10k log pot.

So a dual gang pot can be used like a blendable DPDT, with components soldered between lugs A1 and B1, and A3 and B3?

[rocket88]

Not dual gang, a regular pot. I'm not sure what you're asking about about blending caps. The superfuzz has 2 filters.  the switch chooses 1 or the other, so if you replace the switch with a pot you can sweep between the two filters.

This layout is great, I've made a few of them:

Here is an etchable (or perf) layout of it:

I've made a few of those also. I like this particular Derringer version because it sounds equally great on guitar and bass.

Is it possible to make that same mod with the mids switch of the big muffs?

[rocket88]

Short answer is yes, Lunt not as easy. You'll need to make a spot on the board for the 2 additional caps, or run a  each cap directly from the pot lug to the place the wire would be. Personally the switch is better then having a pot.

Yeah, I meant that more as a general question (not Superfuzz related) but I guess in most cases a regular pot does the blending trick just fine.

The best useful mod I found for the superfuzz tone section was making a "scoop" pot for the tone control, (10k pot between 100nf cap and ground).
